| titleOfInvention | The method of sodium salt or sylvite is extracted from fischer-tropsch synthetic catalyst waste water |
| abstract | The method that the invention discloses a kind of to extract sodium salt or sylvite from fischer-tropsch synthetic catalyst waste water.Method includes the following steps: filtrate is collected: collecting generated filtrate during production fischer-tropsch synthetic catalyst；The processing of first step acid: nitric acid being added into filtrate, dissolves the metallic element sediment in filtrate, forms nitrate solution；Alkali process: alkaline matter being added into nitrate solution, forms alkali neutralization solution, and aging process alkali neutralization solution precipitates the metallic element in alkali neutralization solution；Filtering: the sediment in filtering removal alkali neutralization solution obtains sodium salt or potassium salt soln；It obtains sodium salt or sylvite: obtaining sodium salt from sodium salt solution, or obtain sylvite from potassium salt soln.Above method step is simple, be suitable for large-scale use, which obviate fischer-tropsch synthetic catalyst waste water directly a large amount of exhaust emission ambient enviroments the problem of. |
